Distinguishing Characteristics:

The males of most of the "hanging" clubtails (genus Stylurus) have long, slender abdomens. When perched on leaves, the bodies are pulled down by their weight, creating the appearance of "hanging" clubtails. This greenish yellow, slender dragonfly is striped with black . The body varies from 2.0 to 2.5 inches in length. On the thorax, there are 2 complete lateral black stripes, near base of abdomen, differing from the riverine clubtail's stripes. The face is tawny with blue eyes. The male has the upper face black. At end of the black abdomen, there are large yellowish lateral spots on the club. Along the abdomen, there are small yellow spots on the top. The legs are black.

Shading illustrates monthly percentages of the total flight season records for the species.
Each flight season record is a unique date/location/observer combination where one or more adult or an
exuvia was recorded (excludes nymphs). The actual number of flight season records for each month is shown
in parentheses.

Flight seasons begin earlier in the southern
part of the state, often by a week or more. Also, flight charts may not be accurate for rare species because of
few data available.
